I am having trouble creating an html gallery with a bigger size font. My clients are going to have trouble reading the id #. Please advise how to increase the size and if possible the different font when creating a web gallery.

Which page are you referring to? You'd want to edit either the index.html or media.html file and around the "(iView:Filename)" text put the following: <font size="3">xxxxxx</font>. You can change the size number to meet your needs. If the file name entry already has the font size around it just change the size number as needed.

And where do i do that. I do not know coding or even where to find what you are talking about. I need to change both on the thumnail page as well as the main image. The thing is that this never happened before and I certainly did not do anything differently. What is going on
